This dude Smiler sure knows how to catch our attention with leaks off his upcoming All I Know mixtape. Previously, the U.K. rapper dropped the pretty great "Delorean," which fittingly used a load of Back To The Future imagery in its video. And now, he's heavily sampled Lana Del Rey's cover of Shirley Bassey's "Big Spender" for new tune "Spender." Apparently Del Rey recorded her version of the classic track in the same studio as Smiler, who used her vocals on what ends up being a futuristic, video game-y boom-bap joint. You can stream "Spender" below. All I Know drops Feb. 27. [NME]
